This study aimed to investigate the effects of aromatherapy and music therapy on alleviating anxiety during MRI examinations. The results showed that aromatherapy combined with music therapy can effectively reduce patient anxiety and improve their comfort level during MRI scans.
Objectives Many patients experience anxiety during MRI examinations. However, little attention has been focused on decreasing patient anxiety and minimizing on-site cancellations. Here, we aimed to investigate the effects of aromatherapy and music therapy on alleviating anxiety during MRI examinations. Methods This single-center, double-blinded, randomized control trial was conducted between November 1, 2021, and January 10, 2022. Patients undergoing MRI examinations were assigned randomly into either the aromatherapy group (AG), music therapy group (MG), aromatherapy plus music therapy group (AMTG), or routine care group (RG) at a ratio of 1:1:1:1. Aromatherapy was conducted through inhalation of lavender oil. Music therapy was performed using Pachelbel's Canon in D major. The primary outcome was the change in anxiety before and after the MRI scan, assessed using both the State-Trait Anxiety Inventory form 1 (STAI-1) and Self-Rating Anxiety Scale (SAS). The second outcome was the participant's comfort, measured using Kolcaba's General Comfort Questionnaire (GCQ). Results A total of 200 participants (mean age: 48.3 +/- 14.9 years; 126 [63.0%] females) were enrolled, with 50 per group. The mean anxiety scores of the AMTG showed greater reduction compared with the AG, MG, and RG (Delta STAI-1: 6.5 vs 2.6 vs 2.7 vs 1.9, p < 0.001; Delta SAS: 4.0 vs 1.4 vs 1.7 vs 0.6, p < 0.001). The mean GCQ score of the AMTG was higher compared with the AG, MG, and RG (98.0 vs 92.6 vs 91.2 vs 89.2, respectively, p < 0.001). Conclusion Aromatherapy combined with music therapy is effective for reducing patients' anxiety and improving their comfort level during MRI scans.
